Partial Error Bound Conditions and the Linear Convergence Rate …

(Throughout this paper, by ‘linear convergence’ we mean root-linear convergence, denoted by R-linear convergence, in the sense of Ortega and Rheinboldt .) When there are two blocks ( \(K=2\) ), the convergence of the ADMM was studied in the context of Douglas–Rachford splitting method [ 12 – 14 ] for … Ver mais The augmented Lagrangian dual function can be expressed as For convenience, define p(Ex):=\frac{\rho }{2}\Vert q-Ex\Vert ^2, and let \ell (x):=p(Ex)+g(Ax)+h(x). For simplicity, in this proof we further restrict ourselves to the case … Ver mais By the previous claim, \mathcal {M} is locally Lipschitzian with modulus \theta at (\nabla \ell (x^*), 0)=(E^T\nabla p(Ex^*)+A^T\nabla … Ver mais There exists a positive scalar \theta that depends on A, E, C_x, C_s only, such that for each ({\bar{d}}, {\bar{e}}) there is a positive scalar \delta 'satisfying where {\mathcal {B}} … Ver mais Suppose all the assumptions in Assumption A are satisfied.

MM-ADMM: Implicit integration of MMPDEs in parallel

WebReview 1. Summary and Contributions: This paper studies the Wasserstein distributionally robust support vector machine problems and proposes two efficient methods to solve them.Convergence rates are established by the Holderian growth condition. The updates in each iteration of these algorithms can be computed efficiently, which is the focus of this … WebA new local linear approximation technique is established which enables us to overcome the hurdle of nonlinear constraints in ADMM for DNNs with smooth activations. Efficient training of deep neural networks (DNNs) is a challenge due to the associated highly nonconvex optimization. The alternating direction method of multipliers (ADMM) has attracted rising … WebA standard model for image reconstruction involves the minimization of a data-fidelity term along with a regularizer, where the optimization is performed using proximal … fish central london menu
